Semiconductor device having pairs of pads
View Patent ↗An integrated-circuit semiconductor device includes external electrical connection pads on one face and electrical connection vias under said pads. The electrical connection vias are arranged with a defined pitch in a defined direction. Each via is respectively associated with one of a plurality of adjacent zones of the face. These zones extend perpendicularly to the pitch direction. The electrical connection pads are grouped in adjacent pairs. An insulation space is located between the pads of each pair of electrical connection pads. In a direction perpendicular to the pitch direction, the pads in the pair are spaced apart. The pads of each pair of electrical connection pads extend over a pair of adjacent zones and are associated with two adjacent vias.
